Nuclear transfer from embryonic cell (1 ene 1987 año – 31 dic 1987 año)

Descripción:

Using methods very similar to those used by Willadsen on sheep, First, Prather, and Eyestone produced two cloned calves. Their names were Fusion and Copy. This experiment added cows to the list of mammals that could be cloned by nuclear transfer. Still, mammalian cloning was limited to using embryonic cells as nuclear donors.
